What are percentages

Percentages are similar to fractions with an important difference. In fractions the whole is represented by the denominator (e.g. the number 5 in the fraction of 1/5). In percentages, the whole is represented by the number 100. In fact, 'per cent' means 'per 100' or 'for each 100'.

How to solve

In this example, the number 200 represents the whole and so, as a percentage, it would be equal to 100%. Written as a ratio, we would get: 100% : 200

If a student took a 200 question test and they got every answer correct, as a percentage they would get a 100% score on the test.

In our problem we have to evaluate the 15 percent of 200. For now, let's call this unknown value 'Y'. Written as a ratio, we would get: 15% : Y

To see a relationship between these two ratios, let's combine them into an equation: 100% : 200 = 15% : Y

It is critical that both of the % values should be on the same side of a ratio. For instance, if you decide to put the % value on the right side of a ratio, then the other % value should also be on the right side of its ratio.
